Storage Redundancy (1 / 16): Facebook, our daily scroll-fest, is powered by Azure's Zone-Redundant Storage (ZRS). However, in an act of divine intervention, the Almighty, having grown disgruntled at humanity's fixation with endless scrolling, decides to express His displeasure. A bolt from the blue strikes and burns down their data center in San Francisco! In this divinely dramatic situation, what could be the fate of Facebook's legions of users, thumbing their way to oblivion? Will they continue to share, like, and comment, or are they due for a surprise digital detox?
Answer:
ZRS ensures data is spread across several zones in a region. If one zone goes offline, the others carry on. So, our Facebook loyalists will scroll on, blissfully oblivious to the celestial drama. The other options paint more drastic scenarios than ZRS - a robust choice - would allow.
"A forced hiatus on their social media activities." is not quite accurate because even with one data center under the weather (literally), the remaining zones will keep the network alive.
"The remaining zones will buckle under the data weight" doesn't take into account the resilience of ZRS - the unaffected zones are fully equipped to manage the load.
"A brief moment of digital silence until Facebook Inc. orchestrates a failover to the unaffected zones." isn't the case here, as ZRS doesn't require a manual failover.
"Facebook's misguided choice of ZRS". is incorrect, because ZRS can protect against such occurrences.
